Background

This activity uses IPv6 configurations that include DHCPv6, EIGRPv6, and IPv6 default routing. Your task is to review the requirements, isolate and resolve any issues, and then document the steps you took to verify the requirements.

Requirements

DHCPv6

• Host_A and Host_B are assigned through IPv6 DHCP configured on R1.

IPv6 Routing

• Each router is configured with IPv6 EIGRP and uses AS 100.
• R3 is advertising a summary route to R2 and R1 for the two R3 LANs.
• R2 is configured with a fully specified default route pointing to the ISP.

Connectivity

• Devices should be configured according to the Addressing Table.
• Every device should be able to ping every other device.

Troubleshooting Documentation

Device	Error	Correction
R1	Host_A and Host_B do not get addressing from R1 because the IPv6 DHCPv6 pool is not assigned under the G0/0 interface.	interface g0/0 ipv6 dhcp server R1_LAN
R1	Interface S0/0/1 is configured with the wrong IPv6 address.	int s0/0/1 no ipv6 address 2001:DB8:ACAD:32::1/64 ipv6 address 2001:DB8:ACAD:31::1/64
R1	S3 is connected to the wrong interface of R1.	Switch the cable in the topology from G0/1 to G0/0
R2	The default route has the incorrect next-hop address configured.	no ipv6 route ::/0 GigabitEthernet0/0 2001:DB8:ACAD:F:: ipv6 route ::/0 GigabitEthernet0/1 2001:DB8:ACAD:F::1
R2	IPv6 EIGRP is configured with the wrong autonomous system.	int g0/0 no ipv6 eigrp 1000 ipv6 eigrp 100
R3	IPv6 EIGRP 100 is shutdown.	ipv6 router eigrp 100 no shutdown
R3	EIGRP summary address is incorrectly advertised on S0/0/1.	int s0/0/0 no ipv6 summary-address eigrp 100 2001:DB8:CAFE::/65 5 ipv6 summary-address eigrp 100 2001:DB8:CAFÉ:2::/63 5 int s0/0/1 no ipv6 summary-address eigrp 100 2001:DB8:CAFE::/65 5 ipv6 summary-address eigrp 100 2001:DB8:CAFE:2::/63 5

Verification Documentation

Capture output from verification commands and provide documentation proving that each of the requirements has been satisfied.

Note: Some EIGRPv6 commands are not scored in Packet Tracer v6.0.1. Your Answer will verify that all requirements are met.

Answer’s Note: The answer key for this section is left blank because there are many ways to verify the requirements. For grading purposes, note that the EIGRPv6 summary routes are not graded in Packet Tracer. Also, Packet Tracer does not grade the next hop address in the fully specified IPv6 default route. Check the student’s file to verify configurations.

Suggested Scoring Rubric

Packet Tracer scores 50 points. The troubleshooting documentation and Answer verification is worth 50 points.
